Vedclass · Answer

(C) Isobutylene is $(CH_3)_2C=CH_2$. When isobutylene reacts with concentrated $H_2SO_4 + SO_3$ (oleum),it undergoes electrophilic addition. The $SO_3$ acts as the electrophile,attacking the double bond to form a carbocation intermediate. This leads to the formation of $t-$butylsulphonic acid,which is chemically identical to $2-$methylpropane$-2-$sulphonic acid. Therefore,both names refer to the same product.

Reaction of isobutylene with concentrated $H_2SO_4 + SO_3$ (oleum) gives:
